Abstract

The increased research and development on thermoelectric materials in recent years has been driven primarily by the need for improved efficiency in the global utilization of energy resources. To facilitate the search for new thermoelectric materials, we have developed a high-throughput thermoelectric screening system for combinatorial thin films. This screening system is comprised of two tools, one for measuring the Seebeck coefficient and resistance via an automated multiprobe apparatus, and another for measuring thermal effusivity by a frequency domain thermoreflectance technique. Using these systems, we are able to make measurements for calculating the thermoelectric power factor (S2/p,where S = Seebeck coefficient, p = electrical resistivity) and thermal conductivity of over 1000 sample-points within 6 hours for each instrument. This paper provides examples of our current studies on both oxide and intermetallic materials.
